UNITED STATEs PATENT EDGAR HUSON, OF ITHAOA, NEW YORK, ASSIGNOR TOHIMSELF AND J OHN M. JAMIESO N, OF SAME PLACE.

IMPROVEMENT IN HORSE HAV-RAKE S.

Specification forming part of Letters Patent No. 181,68 1, dated August29, 1876; application filed April 25, 1876. v

unloading the rake; second, to fix the teeth while raking; third, toprevent side motion to the teeth While raking.

These I accomplish, first, by a long hinge, A, with a joint at each end,one end hinged to any convenient place in front of axle, the other eridto the rear of the rake-head, at B B, thus balancing the head and teeth.I then insert shaft 0 into the hinge A at D. The cranks E E are attachedto the head by the connections F F, attached to joint B at G G. Theconnections F are bent so as'to be locked when the cranks are up, by theends being back of shaft 0, as shown by the dotted line; and by a halfrevolution of the shaft 0, the cranks and connections extend and pressdown on the head.

To the wheel I on shaft 0 is secured a chain,

J, one-endof which is attached to the end of bar K, while the other endof the chain is secured to the bar K near its connection with hand-leverO.

The weight of the head H is supported by the hinge A and bar orconnecting-rod F, and

the force tending to depress the hinge A is counteracted by the forceexerted on rod F, which tends to sustain the hinge A.

By moving the hand-lever O the rake may be adjusted to any desiredheight, while the rake-teeth, having a positive connection with the axleof the rake, are made to adjust themselves to any inequalities on thesurface of the field.

The teeth Pare passed through loops or staples in rear of head H. Theypass under and up the front side, through oblong eyes or loops, with anelbow or support to prevent their falling out, thus giving them anindependent motion.

The use of the devices I have invented is apparentto those skilled inthe art to which it appertains.

I claim- 1. The combination, with the hinge A, pivoted in front of. theaxle, and its rear portion resting on the axle, of the rake-head H,connected with the hinge A by means of the connecting-rods F, shaft 0,and pivots 13, substantially as and for the purpose specified.

2. The combination, with the hingeA, constructed and arranged. asdescribed, the rake,

head H, connecting-bars F, and shaft (J, of

the chain-Wheel I, chain J, lever K,'and handlever O, substantially asand for the purpose specified. 1
